Player 1 says what they insert into the slot machine, and Player 2 says what Player 1 recieves from the slot machine, in addition to inserting something in themselves, afterwhich Player 3 states what Player 2 got, and so on.

I've played this before on other forums under the name "The Magic Machine". :o
